Abstract
For evaluating the surface of parabolic mirror (90 mm, F/0.76), two different null test have been discussed. After designing, encoding, and fabricating the CGH(computer generated hologram), the null CGH test was performed. An autocollimation test with a flat mirror was also performed and these testing result were compared.
